Material selection for gaskets used in pressure testing of floating-head heat exchangers
Thread Content
The company currently has a floating-head heat exchanger that requires pressure testing of its pipe ends. Pressure testing is carried out using specialized testing fixtures; however, since NBR rods are used as sealing gaskets, the testing pressure can only reach 2.0 Mpa. What type of sealing gasket material could be used to enable testing at 4.0 Mpa?
I don’t know what your pressure testing fixtures look like
What are the temperature, medium, and pressure?
Check the temperature of that device and the medium. Just use wrapping tape then!
It depends on the type of sealing surface; if it’s RF, a graphite wound gasket can be considered. But if it’s a mortise-and-tenon or male-female fit, it becomes more complicated
